Conditions if Accessories are Installed

This section describes conditions about installation place where accessories are installed. Detailed
installation for accessories (including supported accessory specification, wiring, PCB setting for
accessory configuration, etc) will be dealt in separated chapter.

Thermostat

1. NEVER USE 230V AC Thermostat and 24V AC Thermostat at the same time. If used together, it
causes short-circuit and yields power cut-off by circuit breaker.
2. Some electro-mechanical type thermostat has internal delay time to protect compressor. In that case,
mode change can takes time more than user's expectation. Please read thermostat manual carefully
if the product does not response quickly.
3. Setting temperature range by thermostat can be different with that of the product. The heating or
cooling set temperature should be chosen within the setting temperature range of the product.
4. It is highly recommended that the thermostat should be installed where space heating is mainly
applied.
Following location should be avoid to secure proper operation :
• Height from floor is approximately 1.5 m.
• Thermostat can not be located where the area may be hidden when door is open.
• Thermostat can not be located where external thermal influence may be applied. (such as
above heating radiator or open window)

Remote Air Temperature Sensor

Role and constraint while installation of remote air temperature sensor is very similar to that of
thermostat.
• Distance between the indoor unit and the remote air temperature sensor should be less than 15 m
due to length of the connection cable of remote air temperature sensor.
• For other constraints, please refer to previous page where constraints about thermostat is
described
